Hi:
Are those of you who are using the Ironhorse motors/Hitachi VFD finding, that even with little movement, the motors are running very hot?
I wonder what the life of those will be under this kind of use, as they are not inverter duty motors?
-Gary

I'm not sure I understand, my English is bad. must, necessarily a forced ventilation to cool the engine. in a standard use, the motors do not normally rotate rapidly in one direction and in the other they rotate continuously and the propeller then used to cool the engine.
in the case of a simulator fast movements left / right does not permit cooling so add a fan to cool the engines.
it is any fact it's called a "forced ventilation"
if you have very quick adjustments, AMC and drive, it even warmer.

Also you may need to install braking resistors that absorb the excess power, instead of the motor coils (perhaps the reason the motors are getting hot as well). See the VFD manual for suggested braking resistors to use, usually 300Watt and above. Thanks Thanos

Hi Thanos. Where can i found a cheap brake resistor? My VFD manual ask for 800W (0,75CV motor). Should i use 1 Brake resistor for each motor? Regards talked on the phone about it. I hope its settled now.
